Garrett WollmanBig Storage on #FreeBSD question: suppose you have eight-lane LSI/Avago/Broadcom SAS card (mpr(4)) and a WD Ultrastar Data60 enclosure. If you connect both miniSAS connectors on the HBA to the same IOM on the enclosure, does the HBA actually treat it as a single eight-lane link or is it functionally indistinguishable from connecting each four-lane cable to a different IOM? (We have a decent number of these, despite some peccadilloes it's been our preferred JBOD enclosure for some time.)
